File descriptors 0, 1, and 2 are open to /dev/null (Solaris makes heavy use of symlinks, which is why the pseudo device is shown).

However, a file type mismatch where the filesystem contains a plain file and the database records a device node is harmless; this is how pseudo emulates creation of device nodes.

We then loop, rescanning the SCSI bus (by echoing a command to a special file in the /proc pseudo-filesystem and calling devfsd) until the root device (/dev/sda1 in my case) is present.
